Изобретение относитс к электротехнике и может быть использовано дл коммутации токов в мощных накопител х энергии.The invention relates to electrical engineering and can be used to switch currents in powerful energy storage devices.

В качестве коммутаторов в мощных накопител х энергии наход т применение разр днини с твердым диэлектриком , позвол ющие снизить индуктивность разр дника ввиду машого изол ционного зазора L1.Dischargers with a solid dielectric are used as switches in high-power energy storage devices, which make it possible to reduce the discharge inductance due to the ground insulation gap L1.

Однако при пропускании больших импульсов тока (1 МА), электроды разр дника подвергаютс интенсивному разрушению, что вызывает необходимость увеличени числа канало разр дника.However, when high current pulses (1 MA) are transmitted, the glitter electrodes are subject to intense destruction, which necessitates an increase in the number of the gaps channel.

Наиболее близким известным техническим решением к изобретению вл етс управл емый многоканальный твердотельный разр дник, содержащий два основных электрода, расположенный между ними поджигающий электрод отделенный от одного из,основных электродов, с которым он образует поджигающие искровЕле промежутки, твердым диэлектриком с отверсти ми, а от другого основного электрода - разрушаемым твердым диэлектриком, и запускающий кабель 2.The closest known technical solution to the invention is a controlled multichannel solid-state discharge containing two main electrodes, a burning electrode between them separated from one of the main electrodes, with which it forms spark ignites, a solid dielectric with holes, and the other main electrode is a destructible solid dielectric, and the trigger cable 2.

Недостатком этого разр дника вл етс большой разброс в срабатывании каналов, завис щий от скорости нарастани тока в цепи поджига, чтоThe disadvantage of this discharge is a large variation in the operation of the channels, depending on the rate of increase of the current in the ignition circuit, which

приводит к их ненадежной коммутации.leads to their unreliable switching.

Цель изобретени - поввпдениё надежности многоканального срабатывани разр дника.The purpose of the invention is to ensure the reliability of the multi-channel triggering of the arrester.

Это достигаетс тем, что в известном разр днике количество отверстий в твердом диэлектрике выбрано четным, поджигающий электрод выполнен состо щим из отдельных элементов по числу указанных отверстий,This is achieved by the fact that in a known discharge the number of holes in a solid dielectric is even, the ignition electrode is made up of individual elements according to the number of holes indicated.

напротивкоторых они расположены, оболочка запускающего кабел выполнена с разрывами, а элементы поджигающего электрода образуют пары, причем составные элементы каждойopposite to which they are located, the sheath of the launching cable is made with gaps, and the elements of the igniter electrode form pairs, and

пары подключены к соседним участкам оболочки кабел , образующим ее разрыв,the pairs are connected to the adjacent sections of the cable sheath forming its gap,

На чертеже представлена принципиальна схема предложенного разр дника .The drawing shows a schematic diagram of the proposed array.

Claims

The arrester contains the main electrodes 1, made of separate sections, one of which is under high voltage, and the second is grounded; destructible solid. Dielectric 2, which separates the main electrode from the igniting one, is filled with individual elements 3; A solid dielectric 4 with an even number of holes, insulating under the burning electrode, from the other main electrode, and a trigger cable 5, in the breaks of the shell of which are connected in pairs the elements 3 of the ignition electrode. The capacitors 6 in the diagram represent a capacitive storage device, which is connected to the load through arresters (not shown). The capacitor 7 and the bit 8 are the elements of the trigger circuit. The discharge works as follows. The lower electrode is under voltage, to which capacitor 6 is charged, and the upper electrode is at ground potential. A solid dielectric 2 is designed for full: the charging voltage of a capacitor b When triggering of the surge generator 8, the Starting Current flows through the sheath of the launching cable 5 to one of the elements of the ignition electrode, through the hole in the solid dielectric 4 to the main electrode 1 and further through the adjacent hole to the next element 3 of the ignition electrode and the cable sheath, etc. until the last cable trimming, where the starting current from the shell enters the core. In this case, an arc burns in the holes of the solid dielectric 4, under the action of which the sfteMeHTjoB 3 metal of the firing electrode (copper foil) is ejected and the solid dielectric 2 is destroyed (plastic film), which causes to the triggering of all the channel's channels from one starting current. In order to prevent the intermediate channels from being shunted by the outermost channels, the gap in the shell, the cable and the current lead to the elements of the firing electrode must be performed with a sufficiently low inductance. 4 Thus, the number of channels in the discharge depends on the number of discontinuities of the trigger cable and can be quite large. When using a twelve channel array, the time resolution between the channels according to the contour scheme was tens of nanoseconds. A possible version of the Header is not with sectioned, but with continuous main electrodes. Claims of the invention A controlled multichannel solid-state discharge containing two main electrodes located between them a firing electrode, separated from one of the main electrodes, with which it forms ignition-spark gaps, with a solid dielectric with holes, and from the other main electrode with a destructible solid dielectric. , and a triggering cable connected to the ignition electrode, which is due to the fact that, in order to increase the reliability of the multichannel actuation, the number of holes in the solid and the electric is chosen to be even, the igniter electrode is made consisting of individual elements according to the number of said holes opposite to which they are located, the sheath of the trigger cable is made with gaps, and the elements of the igniter electrode are pair, and the constituent elements of each pair are connected to the Neighboring sections of the cable sheath, -forming its gap.
